The best method I’ve found so far: 1. Get your glasses wet with warm water. 2. Apply dish soap to both lenses. 3. Gently rub the soapy water over the lenses. For some stubborn things (like sunscreen) in the edges I sometimes gently use a Q-tip. 4. Rinse under warm water. Gently rub with your fingers to agitate the soapy water and help rinse it off. 5.

I do similar but use centrafugal forces to spin dry them almost dry with arm swings. Then I use toilet tissue dabbed to get the final few drops off (not wiped!). Toilet tissue can be scratchy so you might want an alternative but for me it's not doing much work and it's always at hand.

I use similar method, except: - Do not apply soap to the lenses. Soap is too thick. Apply it to your fingers and rub between fingers to dilute with a bit of water before applying to glasses. - Use your fingertips as abrasive. Soap is there to dissolve any fats but your fingertips (if clean) are best material to remove anything from your glasses without scratching the surface. - Few faucets give good laminar flow. I j…

I basically do this, but carefully pat dry with either a kleenex tissue or a clean absorbent towel to get the few droplets that inevitably haven't slid off in the not-perfectly-laminar flow.

I've never had a problem keeping my glasses clean. I understand people who take them on/off having problems, but if you just have them on all the time, what are you doing!? I clean mine max once a day, usually can go 2-3 without cleaning. The only time I ran into problems was working with polishing metals. My glasses were getting scratched with the small particles/dust you couldn't even see. I almost thought they wer…

Longer hair I find adds a lot to glasses getting dirty, also windy conditions with dirt blowing in the air

Earlier quoted context omitted.

Glass lenses are only good for spherical prescriptions. If you have astigmatism, you need an aspherical lens, which cannot be shaped in glass.

Thats not true, I have glass aspherical lens.

That you wear for prescription glasses? Unlikely. Glass cannot be shaped into aspheres without very expensive grinding and polishing techniques. Multiple glass shapes are typically molded together to make an aspheric lens. The challenge is that molding the lens this way decreases the Abbe number significantly, which is why it’s not used for prescription eye glasses. If you have astigmatism, your lenses are most likely a polymer of some sort. Check with your optometrist.

I asked the optician how they clean glasses: - Wash with cold water. Warm or hot water might ruin the coating. (Our water comes supercooled right out of the tap in the winter,so in order to not have my hands instantly frozen into a solid block of ice I go for 15—20 degrees or so.) - Use a drop of mild dish soap without ammonia. - Dry them with a soft clean cloth (they use microfiber I think, I just use a random soft…

Wash with cold water. Warm or hot water might ruin the coating. This is why I worry about radiant heat from fires while camping or burning yard debris. Plastic lenses are usually opaque to IR and that means they're heating up even more than you might think.

I once ruined the coating of my glasses by sticking my head into a hot oven to check a disk I was baking. The surface of the lens sort of blistered. From then on I removed my glasses when checking on food in the oven... I also try not to stick my head so far in also.

I usually clean sunglasses by spraying alcohol and wiping with a paper towel. Pharmacies here sell that liquid in small plastic bottles with spray nozzle, the liquid contains 70% ethanol, 30% distilled water.

I know exactly what I have. You can even get glass progressive lenses which are very aspherical. https://lensfactory.com/collections/progressive/products/pro...

I would expect that to destroy many coatings.

What did you use with the ultrasonic cleaner? Just de-ionized water or any solution?

If I recall correctly, first I used to use di water, but later on I used a solution. Whatever protocol is used in biological labs to wash flasks and tubes, I pretty much followed that, I don't remember what washing solution I used, I recall it felt like soapy water. It's possible that latter might have been the problem.

I would expect that solution to be incredibly aggressive. Wouldn't be surprised if it was lye (which feels soapy because it turns the outer layers of your skin into soap).

> A good chunk of people require glasses that need to be custom-made. Zenni makes their glasses to order; what do you mean?

As someone with fairly pronouced Astigmatism in the expensive glasses camp, I'd say: 1) The glasses have to accurately hold my the lens at a specific location and orientation relative to my eyes in order that they actually work. Off by a little bit and it's world of splitting headaches and crazy distortion Achieving that positioning, while dealing with my wonky ears, size of head, eye locations etc - requires knowled…

To your first point: that makes sense!

To your second point: Zenni and competitors do custom grind their orders.
